将Sql Server对象的当前拥有者更改成目标拥有者
数据库操作当中,当数据库对象列表不只有一个普通的元素——objectname时,你将要使用objectowner.objectname来引用对象,但如果需要更改当前数据库中对象的所有者可以使用系统存储过程 sp_changeobjectowner (点击这里更详细)
sp_changeobjectowner
更改当前数据库中对象的所有者。
语法: sp_changeobjectowner [ @objname = ] 'object' , [, @newowner = ] 'owner'. 参数. [@objname =] 'object'.
但往往由于数据库对象过多,希望批处理更改当前数据库中对象的所有者,那么你可以尝试使用Net Fetch的 nf_ChangeObjectOwner 存储过程来完成批处理。具体用法如下:
首先使用以下代码创建存储过程——
nf_ChangeObjectOwner
将Sql Server对象的当前拥有者更改成目标拥有者
语法:nf_ChangeObjectOwner [, @current_Owner = ] 'owner',[,@target_Owner =] 'owner',[ ,@modify_Type=] type
复制代码 代码如下:
if exists (select * from sysobjects where id = object_id(N'[nf_ChangeObjectOwner]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure nf_ChangeObjectOwner
GO
Create PROCEDURE nf_ChangeObjectOwner
@current_Owner nvarchar(255),
@target_Owner nvarchar(255),
@modify_Type int

nf_ChangeObjectOwner
实现功能: 将Sql Server对象的当前拥有者更改成目标拥有者
**** 使用本代码前请备份数据库!
**** 所带来的安全问题,与俺家的驴子无关!
**** 欢迎斧头劈我,劈死偶有奖!
调用方法: Exec nf_ChangeObjectOwner @current_Owner,@target_Owner,@modify_Type
输入参数: @current_Owner nvarchar(255) --对象的当前拥有者
@target_Owner nvarchar(255) --对象的目标拥有者
@modify_Type int --0为默认,更改表的拥有者;1为视图和存储过程
输出参数: RETURN值 = -1 --操作对象为0,操作对象不存在
= -2 --操作失败,可能对象被锁定
= 0(默认值) --操作成功,打印更改对象数目@object_Num
@object_Num --SQL 打印值,返回更改成功的对象数目

Usage(使用方法): Exec nf_ChangeObjectOwner 'dbo','你的用户名',0
——将所有用户表的拥有者更改成'你的用户名'
Usage(使用方法): Exec nf_ChangeObjectOwner 'dbo','你的用户名',1
——将除了用户表之外数据库对象(视图、存储过程)的拥有者更改成'你的用户名'
